Domain specific inbox discovery

[csarven]

Should it be possible to discover domain specific inboxes. Can implementations around generic and specific inboxes be interoperable?

Is there an actual use-case where the generic sender needs to find the specialised inbox and send to it, and similarly receiver to handle that scenario?

[There is a branch which covers the domain specific vocabulary:
